Abstract: Aspects of the disclosed technology provide ways to report User Equipment (UE) device locations in a 5G network for the purpose of redirecting application traffic from proximately located Data Networks (DNs). In one aspect, the disclosed technology encompasses a process for conveying User Equipment (UE) information to an Application Function (AF), the process includes steps for receiving, at an intermediate-User Plane Function (I-UPF) entity, User Equipment (UE) uplink data from a Radio Access Network (RAN), determining if sharing of location information or application information associated with the UE is restricted, and encapsulating first location metadata or application metadata in an SRv6 packet if the sharing of location information or application information is not restricted. Systems and machine-readable media are also provided.

Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.

Abstract: Various implementations disclosed herein enable programming user plane gateway controllers over enhanced N9 interfaces. In various implementations, a method of gateway controlling is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations the method includes determining, by a first packet gateway controller connected to a first session manager device, that a user equipment moved to a geographical area that is served by a second session manager device. In some implementations, the method includes receiving, by the first packet gateway device, a set of information for a second packet gateway device. In some implementations, the method includes transmitting, by the first packet gateway device, a session establishment request via a first network interface to the second packet gateway controller using segment routing via a second network interface.

Abstract: A network function (NF) entity in a communication network receives authentication data associated with a User Equipment (UE), determines the UE supports a blockchain registration procedure based on the authentication data, exchanges authentication messages with a Blockchain Roaming Broker (BRB) entity over a blockchain network interface, receives a blockchain authentication confirmation from the BRB entity, and registers the UE with the core network based on the blockchain authentication confirmation.

Abstract: A Network Function (NF) entity in a telecommunication network receives blockchain credentials associated with UE and selects a Blockchain Charging Function (BCF). The NF entity further generates a Charging Data Record (CDR) corresponding to network resources, and sends a charging request based on the CDR (and policy rules) to the BCF entity over a blockchain network interface. The BCF entity sends a confirmation of the charging request, and the NF entity, based on the confirmation, provisions the network resources to the UE.

Abstract: Methods for selecting network slice, session management, and user plane functions for for user equipment (UE) are described. In one example, a control plane (CP) entity for mobility management may select a CP entity for session management for a session of a UE based on a first set of data items. The CP entity for mobility management may further select a user plane (UP) entity for the session of the UE based on a second set of data items, where second set of data items include at least some of the same data items of the first set. The CP entity for mobility management may send, to the selected CP entity, a message including an identity or indication of the selected UP entity for the session of the UE. The selected CP entity may select the identified or indicated UP entity for use in the session of the UE.

Abstract: In accordance with various implementations, a method is performed at a data plane node with one or more processors, non-transitory memory, and a control interface between a network function module associated with the data plane node and a switch associated with the data plane node. The method includes determining whether an offload capability is available for a data flow received at an ingress network interface of the data plane node. The method also includes determining whether the data flow satisfies offload criteria in response to determining that the offload capability is available. The method includes bypassing the network function module associated with the data plane node and providing the data flow to at least one of the switch associated with the data plane node or an egress network interface associated with the data plane node in response to determining the offload capability is available and the offload criteria is satisfied.

Abstract: Systems, methods, and computer-readable storage media for network association to virtualize network devices using device passthrough. In some examples, a system can determine one or more respective configuration parameters associated with one or more network interfaces on the system. Based on the networking information, the system can map the one or more respective configuration parameters to each corresponding network interface from the one or more network interfaces, to yield mapped interfaces-parameters. Next, the system can record the mapped interfaces-parameters to a data object accessible by a virtual machine on the system. The system can then configure the virtual machine to process the mapped interfaces-parameters as boot time parameters while spawning and launch the virtual machine based on the mapped interfaces-parameters.

Abstract: Method for assisting load-balancing of subscriber sessions in a distributed mobile gateway (e.g. PGW, SGW, ePDG, or TWAG) comprising a plurality of distributed gateway instances (DGIs) is disclosed. Method includes receiving an advertisement of GTP fully qualified tunnel endpoints identifications (F-TEIDs) allocated to a first plurality of subscriber sessions, the sessions assigned to a first DGI of the DGIs. The advertisement indicates the first DGI as a recipient for data provided to the gateway and related to any of the first plurality of sessions. Method further includes storing an association between the GTP F-TEIDs of the advertisement and the first DGI, receiving a packet comprising data related to a subscriber session of the first plurality of sessions, identifying a F-TEID for the data of the received packet, identifying from stored association, that the F-TEID is associated with the first DGI, and forwarding data of the packet to the first DGI.
